U.S. President Trump in Asia: The Big Issues at Stake; New Details of a Church Shooting in Texas; The Sound Annoying Enough to Prevent Car Crashes

CARL AZUZ, CNN 10 ANCHOR: We're taking you across Eastern Asia in our first story today on CNN 10. I'm Carl Azuz. It's great to have you watching.

U.S. President Donald Trump is on a 13-day trip to five countries. In order, it includes stops in Japan, South Korea, China, Vietnam and the

Philippines. The White House says its two main objectives are addressing the nuclear threats from North Korea and discussing international trade.

Both topics came up in Japan, where President Trump spent Sunday and Monday. U.S. and Japan are closed allies. They both been threatened by

North Korea.

And during a news conference, alongside Japanese Prime Minister Shinzo Abe, the American leader echoed something that U.S. Vice President Mike Pence said about North Korea.

DONALD TRUMP, PRESIDENT OF THE UNITED STATES: The era of strategic patience is over. Some people said that my rhetoric is very strong, but look what's happened with very weak rhetoric over the last 25 years.

(END VIDEO CLIP)

AZUZ: North Korean government officials say they're closely watching President Trump's Asia visit. He's scheduled to be in South Korea Tuesday and the Communist North called President Trump a war maniac, and said that if he does anything crazy, North Korea will respond powerfully.

SUBTITLE: Trump in Asia: The big issues at stake.

WILL RIPLEY, CNN INTERNATIONAL CORRESPONDENT: Here in Tokyo, the top priority is the U.S.-Japan alliance. So, you can expect to see Japanese

Prime Minister Shinzo Abe and U.S. President Donald Trump projecting friendship as they tackle two major issues, trade and North Korea.

Over in Pyongyang, officials are still furious over President Trump's speech at the United Nations, when he threatened to totally destroy their country and insulted their leader, calling him rocket man. They're also angry about ongoing joint military exercises. The North Koreans tell me the time for talk is over and it's time to send President Trump a message.

MATT RIVERS, CNN INTERNATIONAL CORRESPONDENT: In Manila, President Trump will meet a fan of his in Philippine President Rodrigo Duterte. The popular but controversial figure has had nothing but praise for the U.S. leader, and the two will discuss Duterte's ongoing war against drugs. The big question, will Trump bring up alleged human rights abuses committed by Duterte's government, of targeting not only drug dealers but drug users as well?

PAULA HANCOCKS, CNN INTERNATIONAL CORRESPONDENT: The priority for South Korea during Trump's visit is North Korea. President Moon Jae-in has gone along with the U.S. policy of sanctions and pressure, but ultimately, Moon wants dialogue. More engagement with the North and it's a desire that in past Trump has called appeasement.

And then, there's trade. Trump has convinced Seoul to renegotiate the trade deal between the two countries, but Seoul doesn't want many changes.

NIC ROBERTSON, CNN INTERNATOINAL DIPLOMATIC EDITOR: President Trump's biggest age old challenge in Vietnam will likely be convincing APEC leaders of his views on free trade. He'll address the Asia Pacific Economic Committee summit, telling him he wants fair trade and balanced trade.

Perhaps the most watched event if it does happens is a possible bilateral between President Trump and President Putin of Russia, although if it does take place, it's slightly to be shrouded by the discussions of Russian meddling in U.S. president elections.

The other events still not on the schedule that may happen, a trilateral between President Xi of China, President Putin and President Trump. Likely

North Korea on that agenda.

RIVERS: The biggest issue for China when President Trump arrives here in Beijing will be North Korea. The Trump administration wants China to do more, to force North Korea to stop developing its nuclear weapons. China says it's doing enough already. That issue will dominate conversations,

though expect discussions over things like trade and opioids as well.

AZUZ: In the U.S. state of Texas, new details are coming to light following a shooting in a small town of Sutherland Springs. Twenty-six people were killed after a gunman opened fire during Sunday's services at the First Baptist Church. The victims range in age from a year and a half to 77 years old. Twenty others were wounded and several were in critical condition last night.

Texas Governor Greg Abbott called the attack the largest mass shooting in Texas' history.

It's not known yet what motivated the killer. He was a 26-year-old man named Devin Patrick Kelley. He was discharged from the U.S. Air Force in

2012 for bad conduct. Investigators say he had domestic problems and had recently shown anger toward his mother-in-law who attends the church.

Governor Abbott says Kelley wasn't supposed to have access to a gun, that he'd applied for a license in Texas but was denied it. Still, police say he bought the rival he allegedly used in the attack from a store last year. And after yesterday's shooting, Kelley was confronted and shot by a resident of Sutherland Springs.

(BEGIN VIDEOTAPE)

UNIDENTIFIED MALE: I saw the shooter coming out about where the cars are parked, and the other gentleman coming from across the street, both had weapons and drawn, and in a matter of half a second, there was exchange of gunfire. It lasted just a few seconds, and the shooter got to his vehicle and took off and the gentleman with a rifle came across the street and said, he just shot at the church and we got to chase him and I said, let's

AZUZ: Johnnie Langendorff also said the shooter eventually lost control of his vehicle and crashed into a ditch. He was found dead by police. It wasn't clear whether Kelley died from a self-inflicted gunshot wound or the original shot by the armed resident.

Officials say 4 percent of Sutherland Springs' population was killed in the shooting. One resident describes the community as a small, Christian town where everybody is close to everybody.

The window cleaning device which was patented in 1903 is the oldest. Rearview mirrors weren't used until years later.

(END VIDEO CLIP)

AZUZ: Some of today's windshield wipers are fully automatic. Some of today's rearview mirrors have screens connected to backup cameras and side view mirrors now feature lights for both turn signals and to indicate if there's a driver nearby. Auto braking, auto high beam control, autopilot,

all examples of who automotive technology has come a long way since Mary Anderson's invention of the windshield wipers.

And as that technology drives forward, so do the sounds it comes with, to make us aware of the cars around us.

REPORTER: Alarms, they're the ones that wake you up in the morning, tell you got a message, that your lunch is ready, to close the fridge door,

BALDWIN: I'm the director of the human factors and applied cognition program at George Mason University.

REPORTER: So, how do you go about creating one of the world's most annoying sounds?

BALDWIN: We started out by going out and getting recordings of actual sounds that were in automobiles currently. Then we took those sounds back to the lab.

REPORTER: Once they collected the sounds, it was time to test on people. They created a system where the listener could --

BALDWIN: Play a sound and then put it in a category --

REPORTER: That the sound was represented.

Either a low urgency like a Facebook notification, a medium range urgency like a check engine, and finally, a high level urgency, like an incoming collision warning.

BALDWIN: And then from there, we set up a series of driving simulator studies and they're driving along and they're doing another task just to kind of give them a distraction component and then suddenly, unexpectedly the car that they're following would break suddenly and we look at their collusion avoidance response, the timing of that.

REPORTER: They created the perfect forward collision warning alarm. And this was really important because?

BALDWIN: We found that the sounds being used currently weren't perfect as being very urgent. You know, a poorly designed sound can be more dangerous than not having a warning at all.

REPORTER: So, thanks for using the most annoying sound to keep us safe.

AZUZ: Earning a perfect "10 Out of 10", Max and Quackers. Sounds like a snack, it's not. Max and Quackers are the names of this dog and duck duo who'd been friends for a long time. After Max's good friend, another Huskie, passed away, his owners acquired Quackers, who also appeared lonely.

So, setting their species aside, these two buddies bonded and had been inseparable ever since. Now, they're an attraction for any passersby in their home of Strout, Minnesota.

So, would you say the duck has gone to the dawgs, or that a dog's life is for the birds? If it looks like a duck, swims like a duck and quacks like a duck, it could be exquackly the kind of dog or duck that fits the bill for a dog's best friend.
